High-Performance DUPLEX
Half-Duplex Communication
EMITTING MODE
This single-chip device operates as
both an Emitter and Detector, and
transmits data over a single fiber in
half-duplex mode — thus reducing
both fiber and component costs when
compared with traditional approaches.

Emitter or Detector in ST
®
Package
Mitel emitters and detectors can be
provided in this low-profile ST
®
package. The device is electrically
isolated from the ST
®
receptacle to
facilitate electrical connection. And
optimum fiber-coupled power or
responsivity is ensured by active
alignment against the fiber.
